When someone contacts me with an electrical problem, one of the first questions I like to ask is “What were you doing/working on when this problem started”. This needs to connect to the group of white wire in the back of the box.
(I now understand the line is power in from the fuse box, and load is to the unit) It appears to be working. I assumed he meant the breaker was marked. This DVD will help you do it right, do it safely AND save money. Remember that one side of the common on the three way is the line side and the other common is the load side or switch leg.
It was hard wired originally to the fuse pannel. He had taken off the wire nut for the neutral wires as part of his testing, and that’s when, to his surprise, he got a shock from the neutral! Check out my YouTube video where I discuss and demonstrate this exact situation described here. Come join the discussion about trade knowledge, tools, certifications, wiring, builds, scales, reviews, accessories, classifieds, and more! This is a line diagram to simplify this further. If you have a 4-way it … GFCI protection is not the same thing as grounding. Normally I bring the line in the top and load out the bottom, but this time I had it the other way and without thinking I cut my load wires to only reach the top lugs.

"If the doors of perception were cleansed everything would appear to man as it is, Infinite. Literally thousands of dollars were spent by Shell Canada to try and solve this mystery. With the switch on, the power travels through the load (in this case, a light bulb filament), and back on the neutral, but no connection to the grounded buss bar, and that is how you get a shock from a neutral! Here’s a diagram to help you understand the situation, and why it happens. With Rob, I found out that he was adding some devices to this circuit, and in another junction box he had taken apart the splices. It is important to check your viral load after you first start treatment or switch to a new regimen to determine if the new meds are working. There should be one wire only under each terminal.
One day I received a call from a friend who was puzzled as to why his light fixture wasn’t working despite the fact that he had 120 volts showing on his meter when he took a reading from the hot wire to ground. Such was the case here. Aside from this little mystery, most electrical anomalies have an explanation. Ask below, or you can comment on the video at my YouTube channel or on my Facebook Page.

The load terminals typically are not visible when you pull the GFCI outlet out of its package because they are covered by a strip of tape (usually yellow in color).
A neutral is the grounded conductor?
In a normal situation with the neutral path intact, you would have 120 volts measured from across the light bulb or the receptacle. Loosen the silver and brass terminal screws on the line side of the outlet. Basically it is like a fuse- it wouldn't matter which was the current travel.
If the wire is coming from the top of the switch box, it is likely your load wire.
Another mystery solved, and a lesson learned! This is one of those ‘tried and true’ tools of the trade that electricians can’t imagine doing their job without.

VerticalScope Inc., 111 Peter, Suite 901, Toronto, Ontario, M5V 2H1, Canada. Standard outlets are much cheaper than GFCIs. If the wire is capable of delivering 30 amps, then the power that’s being delivered is 208 volts times 30 amps times 1.732 for total power available of … One of these is the power feed, and one is the switch leg, but the switch terminals are interchangeable, so there is no need to identify which is which. The line connection is the point where you will connect the incoming feeder wire (also called the line), which is fed from the home’s electrical service panel. Is it dangerous to leave it that way or does it need to be changed?
If you want to understand more about your home’s electrical system, the best tool you can add to your toolkit is “The Basics of Household Wiring” DVD or e-book. This is where the bare or green-colored ground wire connects. Note the switch wiring. How can this be?
The other may be black, red, or white. That particular breaker continued this mysterious behavior and they finally just accepted it, and dealt with these random disruptions. When you connect to both the line and the load terminals, the outlet protects itself and any additional outlets farther down on the same electrical circuit. Introducing "One Thing": A New Video Series, The Spruce Gardening & Plant Care Review Board, The Spruce Renovations and Repair Review Board. it a ghost ……..? This exceptional instructional aid covers most home wiring projects and would be a tremendous addition to anyone’s toolbox. For man has closed himself up, till he sees all things thro' narrow chinks of his cavern.” William Blake, It will still function fine, and is legal to do, but I believe it has to be marked as such. The black wire is the hot wire, the one you should never touch with the power on. I needed to install a cut off switch close to the unit.
Terry Peterman, the Internet Electrician®. Without a continuous path back to the panel, and the neutral buss bar, the voltage has no place to go to complete the circuit. Timothy Thiele is an electrician who advises residential DIYers on how to make home installation projects safe and easy. The markings for line and load usually are printed on the back of the outlet's plastic body. The other cable connects to the LOAD terminals to bring power downstream to additional outlets and other devices on the circuit. What is a loaded neutral, and why did I get a shock from it? In some cases, line wires are marked with “line”, “pwr”, or a lightning bolt symbol. JavaScript is disabled. If the breaker itself is not marked, by the manufacturer, "line" and "load", then you can feed it either way.
The two wires that connect between the 3-ways switches are carriers. Correction: never touch any wire with the power on, and use a meter to double check they are all off before touching anything.
With the switch on, the power travels through the load (in this case, a light bulb filament), and back on the neutral, but no connection to the grounded buss bar, and that is how you get a shock from a neutral! The circuit's hot wire (typically colored black or red) connects to the black or brass-colored screw terminal marked LINE.
The load connection is available to feed additional standard (non-GFCI) outlets downstream from the GFCI location to provide protection from the GFCI. Line Connection The line connection is the point where you will connect the incoming feeder wire (also called the line), which is fed from the home’s electrical service panel . If the circuit wiring does not contain a ground wire, the GFCI will not be affected and will operate as designed, but the outlet will not be grounded. You mentioned two black wires.

He had 120 volts on both sides of a switch (turned on) feeding a light fixture, but the light wasn’t working. And you [can] connect line 3 to line 1 and get 208 volts. Have questions about this or any other electrical project? Read on to hear about a situation that I experienced recently in which a friend encountered an open or loaded neutral while doing some DIY wiring and needed some help understanding what caused the situation. Using the load connection requires two cables in the GFCI's electrical box. When you connect only to the line terminals, the outlet provides GFCI protection only for itself. That’s when I knew he was dealing with an open or loaded neutral.
When working in the oil industry back in Alberta Canada, we had a situation where a high voltage breaker feeding a large electric motor would randomly trip. So he tested with his meter, and sure enough, 120 volts to ground!
